IMPROVEMENT IN HUBS FOR VEHICLE-WHEELS.

Specification forming part of Letters Patent No. 158,737, dated January12, 1875 application filed October 24, 1874.

To all whom it may concern:

Be it known that I, ADAM N. PRICE, of Jamestown, in the county ofChautauqua and State of New York, have invented a new and valuableImprovement in Vehicle Wheels and Axles; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure l of the drawing is a representation of a vertical sectional viewof my vehicle wheel and axle. Fig. 2 is a detail view. Fig. 3 is a rearview. Fig. at is a plan view, and Figs. 5, 6, 7, and 8 are detail views,of the same.

This invention relates to an improvement in lubricatingaxles withoutremoving the wheels therefrom; also in dodging or staggering the spokesin a two-part hub in such manner that the spokes can be tightened whentheir tenons shrink, all as will be hereinafter explained.

The following is a description of my improvements In the annexeddrawings, A designates the axle, and A the journal thereof, in whichlatter is an oil-hole, a, which enters at the outer end of the journal,and communicates with the interior of the pipe-box B by means of across-passage, a, at or near the middle of the length of the journal, asshown in Fig. 1. Oil is supplied to the receptacle a through a hole,which is made through a screw-cap, O, which hole is tightly closed by ascrew-plug, 9, thus excluding dust and other foreign matters. Thepipe-box D, on which the cap 0 is screwed, is constructed with anannular flange, e, on its inner end, which flange is drawn tightlyagainst a shoulder, e, in the inner end of a hub-section B, by means ofsaid cap 0. The pipe-box D is prevented from rotating in the sections BB, by means of pins 13 i on the section B fitting into notches 0 made inthe periphery of the flange 0, shown in Fig. 3. G designates a hollowscrew plug, which is tapped into the inner end of the hub-section B forthe purpose of confining a packing, h, against a collar, f, on the axle,and thus excluding dust and keeping in the oil. The adjoining faces ofthe two hub-sections B B are constructed alike to receive the tenons Jon the spokes J, which spokes are inserted staggerin g or zigzag intothe mortises a between the tenons n. The tenons n on one section are ofsuch width that they will snugly enter the recesses or mortises n of theother section, so that when the two sections are drawn together, afterthe spokes have all been inserted the tenons n will interlock with oneanother, and they will bear hard on the spoketenons, so as to clamp andfirmly hold them in their places. By this arrangement the tenons of thespokes can be made of any desired thickness, and when they shrink, byscrewing up the cap 0, they can all be properly tightened again. For thepurpose of more firmly securing the spoke-tenons J in their mortises,these tenons are made dovetailing, as shown in Figs. 1 and 6, and themortises are made of a corresponding shape. As a still further security,Imake indentations or annular grooves, or serrations, indicated byletter I) in the surfaces of the tenons n, which will impress themselvesinto the surfaces of the spoketenons J when the sections B B areforcibly clamped together, as described, and thus prevent displacementof the spokes under the roughest usage.

Fig. 7 shows the cap G applied on the outside of the hub, and Fig. 8shows a spiral oilfeeding groove on the outside of the journal A, whichmay be used in combination with the groove a, or it may be used alone.

What I claim as new, and desire to secure by Letters Patent, is-

1. The journal A, having the oil-passages a a, and collar f, incombination with the nut Gr, pipebox D, cap O, and screw-plug 9,substantially as and for the purpose set forth.

2. The pipe-box D, having an annularfiange, c, on its inner end,provided with notches 0, in combination with the hub-sections B B, pins5 i, nut G, and cap U, substantially as and for the purpose set forth.

3. The hub-section B, provided with the tenons n and mortises n, havingprojections b b, in combination with the similarly-formed hub-section B,the tenons of which break joints with those in the opposite hub-sectionB, and spokes J substantially as andfor the purpose set forth.

In testimony that I claim the above I'have hereunto subscribed my namein the presence of two witnesses.
